mqttx-cli skillA
mqttx-cli is agent-read markdown (skill) from emqx/mqttx: Use MQTTX CLI for MQTT connections, publishing and subscriptions, MQTT 5 features, TLS and SCRAM authentication, payload codecs and schemas, benchmarks, built-in or custom data simulation, configuration, installation and troubleshooting. Use when operating or testing MQTT through the mqttx command. Does not operate MQTTX Desktop or administer a broker..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# MQTTX CLI ## Prepare 1. Locate `mqttx`, read `mqttx --version`, then inspect `mqttx <command> --help` for the task. Treat installed help as authoritative; release channels can differ. If missing or a required feature is unavailable, follow the repository's root `INSTALL.md`, or its [standalone installation guide](https://github.com/emqx/MQTTX/blob/main/INSTALL.md) when this skill has been copied elsewhere. Do not update a working CLI on every invocation. 2. Establish the broker hostname, port, transport (`mqtt`, `mqtts`, `ws`, `wss`), MQTT version, credentials, topic and intended operation from the user's context. Ask only for missing information that affects execution. Use the requested broker; do not substitute a public broker after a failure. 3. Account for `~/.mqttx-cli/config`, which can supply default host, port, protocol and credentials. Do not print its secrets or overwrite it for a one-off task. Explicit CLI arguments override defaults; `--load-options` loads command-specific JSON/YAML options, with explicitly supplied CLI arguments taking precedence. See [configuration and utility commands](references/configuration.md) for initialization, saving and loading. …
